Chrysanthemum plant named Autumn Moon

ABSTRACT

A new cultivar of  chrysanthemum  plant botanically known as  Chrysanthemum×morifolium,  and commercially referred to by the varietal name ‘Autumn Moon’. The new cultivar has a single flower form with pale yellow ray florets and a hint of pink in the ray florets, uniform habit and flowering response that is late, strong stems, medium green foliage color, good garden habit, and excellent shelf life.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT NAMED

Chrysanthemum×morifolium

VARIETY DENOMINATION

Autumn Moon

FIELD OF THE INVENTION

The present invention relates to a new Chrysanthemum plant botanicallyknown as Chrysanthemum×morifolium, and hereinafter referred to by thevarietal name ‘Autumn Moon’.

BACKGROUND OF THE INVENTION

‘Autumn Moon’ is a product of a planned breeding program that focuses onobtaining new cultivars of garden chrysanthemums in a range of flowercolors that bloom late in the season after other fall mums have passed.These plants exhibit superior winter hardiness suitable for northernclimates and provide much needed food for bees and beneficial insects.

‘Autumn Moon’ originated from an open pollinated cross in 2005 atDunvegan Nursery in Coatesville, Pa. The female parent was the speciesChrysanthemum indicum, a semi-double daisy form with yellow and pink rayflorets, and medium upright habit. The male parent of ‘Autumn Moon’ isChrysanthemum×koreanum ‘Sheffield’, with single flowers of pink floretcolor, and a well-branched habit, producing an abundant amount ofpollen. ‘Autumn Moon’ was selected as one flowering plant within theprogeny of the stated cross in November 2005, and grown out of doors inCoatesville, Pa.

The first act of asexual reproduction of ‘Autumn Moon’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inApril 2008, in a controlled environment in Coatesville, Pa.

SUMMARY OF THE INVENTION

‘Autumn Moon’ has a single flower form with pale yellow ray florets anda hint of pink in the ray florets, uniform habit and flowering responsethat is late, strong stems, medium green foliage color, good gardenhabit, and excellent shelf life.

Horticultural examination of plants grown from cuttings of the plantinitiated in April 2008 and continuing thereafter, has demonstrated thatthe combination of characteristics as herein disclosed for ‘Autumn Moon’are firmly fixed and are retained through successive generations ofasexual reproduction.

‘Autumn Moon’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

‘Autumn Moon’ has not been made publically available for more than oneyear prior to this filing.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes ‘Autumn Moon’ from all other varieties ofchrysanthemum known to the inventors.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS/DRAWINGS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Autumn Moon’ with colors being as true as possiblewith an illustration of this type.

FIG. 1 shows a plant of the cultivar in full bloom;

FIG. 2 shows the various stages of bloom of the new cultivar; and

FIG. 3 shows the foliage of the new cultivar.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in St. Albans, Vt. inOctober 2010 under greenhouse conditions. The aforementioned photographswere taken in a studio in St. Albans, Vt. in October 2010. The plantswere started and grown in Coatesville, Pa., then shipped to St. Albans,Vt. in July 2010. Plants were grown under greenhouse conditions typicalfor herbaceous perennial plant production. Color references are made toThe Royal Horticultural Society Colour Chart (R.H.S.) 2007.
